【问题描述】：

我正在使用 this heroku walkthrough 开始使用 node.js。我已经完成了，现在我想将数据从远程数据库拉到我的本地版本。

我刚刚按照here 的说明运行$ heroku pg:pull HEROKU_POSTGRESQL_[mycolor] mylocaldb --app [myappname]，它返回了一堆pg_dump 和pg_restore 消息。

pg_dump: reading schemas
pg_dump: reading user-defined tables
pg_dump: reading extensions
pg_dump: reading user-defined functions
pg_dump: reading user-defined types
pg_dump: reading procedural languages
pg_dump: reading user-defined aggregate functions
pg_dump: reading user-defined operators
pg_dump: reading user-defined operator classes
pg_dump: reading user-defined operator families
pg_dump: reading user-defined text search parsers
pg_dump: reading user-defined text search templates
pg_dump: reading user-defined text search dictionaries
pg_dump: reading user-defined text search configurations
pg_dump: reading user-defined foreign-data wrappers
pg_dump: reading user-defined foreign servers
pg_dump: reading default privileges
pg_dump: reading user-defined collations
pg_dump: reading user-defined conversions
pg_dump: reading type casts
pg_dump: reading table inheritance information
pg_dump: reading event triggers
pg_dump: finding extension members
pg_dump: finding inheritance relationships
pg_dump: reading column info for interesting tables
pg_dump: finding the columns and types of table "test_table"
pg_dump: flagging inherited columns in subtables
pg_dump: reading indexes
pg_dump: reading constraints
pg_dump: reading triggers
pg_dump: reading rewrite rules
pg_dump: reading large objects
pg_dump: reading dependency data
pg_dump: saving encoding = UTF8
pg_dump: saving standard_conforming_strings = on
pg_dump: saving database definition
pg_dump: dumping contents of table test_table
pg_restore: connecting to database for restore
pg_restore: creating SCHEMA public
pg_restore: creating COMMENT SCHEMA public
pg_restore: creating EXTENSION plpgsql
pg_restore: creating COMMENT EXTENSION plpgsql
pg_restore: creating TABLE test_table
pg_restore: processing data for table "test_table"
pg_restore: setting owner and privileges for DATABASE dfm6qsm6f0l9kh
pg_restore: setting owner and privileges for SCHEMA public
pg_restore: setting owner and privileges for COMMENT SCHEMA public
pg_restore: setting owner and privileges for EXTENSION plpgsql
pg_restore: setting owner and privileges for COMMENT EXTENSION plpgsql
pg_restore: setting owner and privileges for TABLE test_table
pg_restore: setting owner and privileges for TABLE DATA test_table

现在当我访问 /db 路由时，我仍然收到此错误消息：

Error error: relation "test_table" does not exist

我还需要做什么才能正确提取这些数据？

【解决方案1】：

我只是从我的本地应用程序访问远程 Heroku Postgres 数据库，我认为，正如 Heroku 所希望的那样，FWIW。但我认为 Heroku 没有做正确的事情。我像这样破解了我的设置：

Trouble Accessing Remote Postgres DB on Heroku from Local Node.js Webapp

鉴于其他帖子表明，我不确定这是最好的长期解决方案，但我对此没有任何问题。
